Haiku OS GRUB2 menu entry

Haiku is the current continuation of the old discontinued BeOS system. I had the BeOS installation CD a long time ago and played with it a little when it came out. It didn’t catch on and sort of fizzled out. But lived on as an open-sourced Haiku.

I was surprised to find Haiku as a form of BeOS still hanging around the internet. I have been curious about the various OS that have been developed and how the usability of the different OS compared against the big giant Microsoft and the interesting Linux OS.

LibreElec GRUB2 menu entry for booting

I first learned about LibreElec when I got my Raspberry Pi 4. Having played around with it to watch some movies and connect to Netflix, YouTube and Spotify in the little RPi SBC, I was thinking of installing it on my spare old PC.

LibreElec has a simple Linux shell making it very lightweight. It just concentrates on being a media player by running Kodi fully.

FossaPup Puppy Linux GRUB2 menu entry

Puppy Linux is one of the most handy of the super light linux and considered my goto distro whenever I need to make changes, edit files, and copying files or moving files between distros and between partitions. It dispenses with the need to key in sudo privileges because it is already considered as root and has no issue whatsoever when I need to access another Linux partition.

GRUB2 Menu Entry Manually Set Up For Non-Detected Linux & Other OS

My earlier post about super multi-boot using Linux GRUB2 as my main boot loader and menu selection had been fun to do! There were also some tricky issues such as some OS need to be installed first before Linux and other OS could be installed.

Now we come to the issue of those Linux OS that could not automatically be detected by way of issuing terminal command ‘update-grub’ and had to be manually written into the GRUB configuration. I scoured the web for the commands and there were some variations to the menu entry. In some cases, some amount of tweaking was required in order to get it to work.

How Much Hard Disk Space to Allocate for each Linux and Windows Multiboot OS

During my preparation for a super multiboot computer, I needed to know how much hard disk space to allocate for the various Linux, DOS/Windows and alternate operating systems. These were usually easy to check by visiting each of the distros websites. Anyway, I took some gparted partition manager screenshot of my hard disk, hopefully this would give a fair idea of how much space each distro used up.

How To Build a Super Multi-Boot Linux OS

Having cleaned up several of my old PCs, I’ve decided to embark on my next project. To make a super multi-boot OS system with Linux, DOS, Windows XP and alternate operating systems. Dual-booting is fairly easy, but multi-booting with 10 OSes, now that would be a feat! In order to cram in so many OS, some prior preparation would be needed. Since these are old PCs with Pentium 4, Dual-Core and Core 2 Duo, I would need to look for pretty lightweight Linux. I also wanted some alternative non-linux, non-Windows OS.

Cleaning Up Dusty Computers

I have a bunch of old computers which I would like to repurpose for experiments and other tasks. These old PCs were given to me by family members and some were salvage from the office. These were more than 10 years old and they were no longer capable of running the latest Windows 10. However they were still capable of running light weight operating system like Linux.

However before I could reuse them, I needed to clean them out as the dust accumulated inside was like a mini grey moss jungle, well one of it anyway. The rest had dust in hard to reach corners and on the board itself. Since they were old, I decided to do some drastic cleaning measures. I think most technician would've frown at my methods, but I found it to be truly effective! However a very thorough cleaning was no easy task and it took me the better part of an entire day to clean up one PC. With so many old computers at my disposable, it spanned several weekends just to clean them up! Fortunately with the pandemic lockdown and working from home, I have some spare time after hours to tinker with my various hobby projects!
